Without a first class system of interstate highways, life in America would be far different -- it would be more risky, less prosperous, & lacking in the efficiency & comfort that Americans now enjoy & take for granted. The Dwight D. Eisenhower System of Interstate & Defense Highways, in place & celebrating its 40th anniversary, must surely be the best investment a nation ever made. Consider this: it has saved the lives of at least 187,000 people; it has prevented injuries to nearly 12 million people; it has returned more that $6 in economic productivity for each $1 it cost, & much more. Photos. Charts & tables.

Discover the twists and turns of one of America’s great infrastructure projects with this “engrossing history of the creation of the U.S. interstate system” (Los Angeles Times). It’s become a part of the landscape that we take for granted, the site of rumbling eighteen-wheelers and roadside rest stops, a familiar route for commuters and vacationing families. But during the twentieth century, the interstate highway system dramatically changed the face of our nation. These interconnected roads—over 47,000 miles of them—are man-made wonders, economic pipelines, agents of sprawl, uniquely American symbols of escape and freedom, and an unrivaled public works accomplishment. Though officially named after President Dwight D. Eisenhower, this network of roadways has origins that reach all the way back to the World War I era, and The Big Roads—“the first thorough history of the expressway system” (The Washington Post)—tells the full story of how they came to be. From the speed demon who inspired a primitive web of dirt auto trails to the largely forgotten technocrats who planned the system years before Ike reached the White House to the city dwellers who resisted the concrete juggernaut when it bore down on their neighborhoods, this book reveals both the massive scale of this government engineering project, and the individual lives that have been transformed by it. A fast-paced history filled with fascinating detours, “the book is a road geek’s treasure—and everyone who travels the highways ought to know these stories” (Kirkus Reviews).

Examines the construction of the interstate highway system.

This report, prepared by the Public Works Historical Society with some minor editing by AASHTO, outlines the origins of the Interstate and Defense Highway System, the early years of its implementation, and the challenges and adjustments required in its completion.

All phases of road developmentâ€"from construction and use by vehicles to maintenanceâ€"affect physical and chemical soil conditions, water flow, and air and water quality, as well as plants and animals. Roads and traffic can alter wildlife habitat, cause vehicle-related mortality, impede animal migration, and disperse nonnative pest species of plants and animals. Integrating environmental considerations into all phases of transportation is an important, evolving process. The increasing awareness of environmental issues has made road development more complex and controversial. Over the past two decades, the Federal Highway Administration and state transportation agencies have increasingly recognized the importance of the effects of transportation on the natural environment. This report provides guidance on ways to reconcile the different goals of road development and environmental conservation. It identifies the ecological effects of roads that can be evaluated in the planning, design, construction, and maintenance of roads and offers several recommendations to help better understand and manage ecological impacts of paved roads.
